וַיִּסַּ֤ע יִשְׂרָאֵל֙ וְכָל־אֲשֶׁר־ל֔וֹ וַיָּבֹ֖א בְּאֵ֣רָה שָּׁ֑בַע וַיִּזְבַּ֣ח זְבָחִ֔ים לֵאלֹהֵ֖י אָבִ֥יו יִצְחָֽק׃
At naglakbay si Israel kasama ang lahat ng kanyang pag-aari, at dumating siya sa Beerseba, at naghandog siya ng mga hain sa Diyos ng kanyang amang si Isaac.
Shulchan Arukh, Yoreh De'ah
A person is obligated to honor his father-in-law. Rema: And some say that a person is not obligated to honor his grandfather, but this does not appear correct to me. Rather he is obligated in the honor of his father more than that of his grandfather (Maharik, Root 44). (And the proof is from the midrash regarding [Gen 46:1], "and he offered sacrifices [to the God of his father, Yitzchak]").
